Claims. (01. 280-1135) I This present invention relates to aski harness of the hinge action type The main object of my invention is the design of a .ski .harness having a rigid partfixed to the ski, that is adjustable to various sizes of boots, including rubber, boots, isof simple construction and may be manufactured at low cost.

It is a further object of this invention .to design a ski harness having toe plates which because of their swivel mounting prevent the cutting of rubber foot wear and thatis so constructed that pressure in turning. and twisting the ski is applied at the heel as well as at the toe.

In the drawings:

Figure 1 is aside view of my ski ,harness at- 1 .tached to .the foot;

Figure 2 is.a top plan View; Figure 31s a central longitudinal section; Figure 4 is a bottom plan View;

Figures 5,and Gare enlarged transverse vertical sections on line 5.5 and 69 respectively of Fig- ,ure 2;

Figure 7 is.a transverse section on line l---'! of Figure 1;

Figure 8 is a vertical'detailsection through one .of the rear stops of the heel on line 8-8 of Figure 2.

.In the drawing in which like reference characters designate like or similar partathere is shown at! thevcentral portion of .the ski preferably of wood which supports a heel 3 of any suitable material preferably metal.

The bottom surfaced of ,the heel 3 is preferably corrugated to prevent .lumpingofjthe snow. An aperture 5 extends horizontally and lengthwise through the heel to house a guide 6 which extends forwardly and is pivoted at the forward end to a plate I. The latter is secured upon the horizontally offset portion of a foot member 8 the lower portion of which is securedby suitable fastening means to the upper surface of the ski. A bridge member I!) is secured to the top'of plate 7, ex tends forwardly in parallelism to the ski and is secured to the horizontally offset portion of foot member II which is secured to the ski member.

The rounded rear portion of the heel is provided with apair of symmetrically arranged stops l2 which take the'form of an angle iron held in a hollow of the heel .bysuitable fastening means l3 and having a pair of legs the outer ends of which protrude beyond the heeland are bent upward (Figures 1, 2 and 8).

The heel is further provided with a horizontal transverse aperture in which the horizontalportions ofclamps I4 can slide. The latter include upstanding portions and headed pins IE-secured to the lower side adjacent the inner confronting ends of the: horizontal clamp zportions'iand each :slidable in-one of a pair of rearwardly converging :slots 16 formedin a rigid end portion llof. aestrip of belting l8, bothoverlyingtheguide B. The belting extends forwardly over the top-surface of the bridge and in a depression l9 (Figure 5) -in the .latter and then beneath inwardly extending spaced flanges 20 formed on the bridge member (Figures 2 and 7). The front end-of the belting is secured :to the bottom surface of a plate-2i 'of a width to fit between the inner edges of the flanges. --From the front and rear edges of this plate rise bosses 22 in which ascrew shaft 23 is journaled. A nut '24 is threaded upon the shaft and has in its upperportion a hole for a 'horizontally disposed pivot pin 25 whichalso passes through thebifurcations of a lever 26 which is off set rearwardly and thenfor-wardly.

The forward portions 21 of the fianges'described are .bent upward and apertured for the passage-0f short -bolts 28, each of which also passes through the terminals of theou-twardly diverging arms of a yoke 29. In the parallel portions of thesearms is pivoted acentrally apertured piv'otbolt 30. The outer portion of lever 26 beyond the second bend passes through the aperture in the bolt and is encircled-by. acoil spring- 3| bearing Withone end against the-bolt and with the other end against. a nut 32--the turning-of which "will vary the tension of the spring, upon the free end of the lever.

The intermediate portion of the bridgeis supported-by a transversely apertured block 33. into the two ends of .this openingare-threaded screws 34 afterrpassingthrough nuts 35 which have inwardly extendingfguide :portions 36 slidable between the -upper surface of the block and the overhanging undepressed flanges-of :the bridge and carrying by vertical. pivots 31 on their upper surf aces the horizontal portions of. upstanding toe clamps 38. The upper ends of the-latter-are conneoted'by astrap-39. A similar strap connects the upper ends of the heel clamps M. Each of the straps 39 is of a conventional construction ineludingv complementary end portionswhich are adj ustably connected-by-asuitable buckle or. fastening, not shown.

The toe clamps 38 need only -be-adjusted once ordinarilyfor :use by a skier-and which may be readily accomplished by the sole of the shoe being positioned on the bridge member Hl and vwith the heel "resting ,zonthe heel block :3 and abutting .against the heel stops 12, as illustrated in Figure 1 except that the'heel block '3 will :be resting on the top surface of'the ski-v portion 2. The two toe clamps 38 are then positioned in abutting engage- "ment'with the sideedges of the sole of the sk-iers shoewafter-which -.the screws 34 are advanced throughthenuts..35 into engagementwith the transverse threaded bore of the block 33"so that the parts :will be in the positions asillustrated in Figure B and correctly adjusted to fit the shoe sole. The toe strap 39 may then be properly adiusted to ;fitr -snugl rg;across the .upperlzsurface 'of the toe portion of the shoe and the heel of the shoe may then be elevated relatively to the block 3 and out of engagement with the heel stops l2 so that the toe portion of the shoe may then be extracted rearwardly from a position between the toe clamps 38 and beneath the toe strap 39. Thereafter, in applying and securing the shoe encased foot to the ski, the toe portion is inserted between the toe clamps 38-and beneath the toe strap 39 and as it is advanced forwardly or from left to right of Figure l the side edges of the sole will engage the forward edges of thetoe clamps for causing said clamps to oscillate about their pivots 31 and to be thereby brought into flush engagement with the side edges of the shoe sole and when thus disposed the toe strap will be positioned relatively tight across the upper surface of the toe of the shoe and the shoe will be disposed so that the shoe heel and rear portion of the shoe may be swung downwardly to position the shoe heel against the heel block 3 and in abutting engagement with the heel stops l2. These operations are accomplished while the toggle lever 29 is swung upwardly and rearwardly from right to left of its position of Figure 3 so that the belting l8 and its rigid end portion H will be displaced rearwardly or from right to left of their positions of Figure 3, in order that the heel clamps M will be displaced laterally outwardly of one another to spread positions by the cam means I5, I6. Accordingly, after the heel has been positioned against the block 3 the toggle lever 29 is swung forwardly or back to its position of Figure 3 to thereby displace the belting l8 and its rigid portion l1 forwardly or from left to right of Figure 3 so that the heel clamps [4 will be drawn inwardly of one another by the cam means l5, l6 and into clamping engagement with the side edges of the shoe heel. Thereafter, the heel strap ends may be buckled across the instep of the shoe to complete the fastening of the shoe to the ski.

In removing the shoe from the ski, the rear heel strap 39 is first unfastened and the toggle joint lever 29 is then swung rearwardly or from right to left of Figures 1 and 3, as previously described, to displace the heel clamps l4 away from one another, as aforedescribed, so that the shoe heel can be lifted out of engagement with the stops [2 and the shoe then displaced rearwardly out of engagement with the toe strap 39 and toe clamps 38, as previously described.

While I have above described in detail the specific embodiment of my invention illustrated in the accompanying drawings, I do not desire my invention to be limited to the particular construction disclosed and I intend in the appended claims to cover all modifications within the spirit and scope of my invention.
